Editor: isual BNF is a FREE parsing tool for noncommercial use - BNF parser, which is used to generate an LALR / LR (left to right parsing with rightmost derivated syntax tree) tables and DFA (deterministic finite automata) states. This is common Parser Generator.
This product offers visual coding of BNF (Backus Naur form) syntax, compilation and generation of output parse table dll (dynamic link library), which then can be integrated with Your application.
Visual BNF offers also testing of the new language specified in a BNF syntax to see how it works. Syntax tree is also available there as new language is being parsed.
This product was named Visual BNF because most of time you might visual parse code and see dynamic syntax tree of tested grammar.
Design
Visual BNF uses LR(1) and LALR(1) (switchable manually) Algorithm to analyze syntax and deterministic finite automaton to identify different class of tokens. The LALR and DFA tables are easy to implement since they rely on lookup state tables.
